Web Services are a standardized way of communication between a client application which consumes e.g. information from a server application in service-oriented architectures. SAP NetWeaver Application Server ABAP can be used both as a provider and a consumer of Web services. You can create, configure, publish, and consume services.
The communication using web services needs to be monitored for errors and performance issues to ensure a smooth information flow.
Performance measurements are based on Real-User Monitoring (RUM) which is also a part of SAP Focused Run. When Web Service performance monitoring is set up, RUM is automatically configured in the background.
To be able to monitor interfaces of an on-premise system you first have to add it to Interface & Cloud Monitoring and select the monitoring categories you want to monitor for the system.
In the next step, you see all monitoring categories which are available for the system, depending on the system type and the installed software components. Some recommended standard monitoring categories are preselected.
Select the monitoring categories in scope.
Available Monitoring Categories
For Web Service Monitoring, different monitoring categories are available:
For the category 'Web Service Messages (ABAP)' you can collect payload information from the web service message and display this payload in the AIM application in SAP Focused Run. You can then use this information to search for related messages in PI or CPI, related IDocs, or related web service calls. Find out how to set up the collection of payload information here.
After selecting your monitoring categories you have to maintain filters to define what exactly you want to monitor. Some monitoring categories come with standard filters that usually just select all items of this monitoring category. SAP Focused Run can handle this high amount of monitoring data, so you can stick to this standard filters. Or you can set up filters of your own.
Please note that the filters you set in the 'Monitoring' step filter the data which is collected from the managed system or cloud service. You can also set up filters later in the 'Alerting' step, which will filter the data already in Focused Run.
You can create more than one filter for a monitoring category.
Available Filter Options
For all monitoring categories, you can opt to use the default filter, that collects all web service communication. You can also use the following filters to restrict the web service communication:
Web Service Messages (ABAP)
Web Service (Performance)
ABAP Web Service Consumer
ABAP Web Service Provider
The setup of the filters for the monitoring categories only makes sure that the data is collected, however, alerts are not created automatically. To create alerts and notifications you have to create an alert individually.
In the next sub-step, you have to maintain the filter. For most monitoring categories the available filter fields will be the same as for the 'Monitoring' configuration described above.
For some metrics, you have additional filter fields or you have to maintain metric parameters. You can check the collected data in Focused Run to determine which filter values to use for alerting. Most of the fields can be found in the Collection Context of the collected data.
Please note that the filters on 'Alerting' level filter the data that is already available in Focused Run. They do not influence the data collection itself. You can only filter for data that is collected. Be aware of this if you created strict filters in the 'Monitoring' step.
In the last sub-step you have to activate the alert:
For single exceptions, the threshold type is always 'Already Rated'. This means depending on the calculation frequency the number of exceptions is checked and an alert is created if this number is bigger than 0. If you want to reduce the number of alert for these metrics, you could increase the value for the calculation frequency to increase the time between checks.
Available Metrics
The following metrics are collected for the different web service categories:
Web Service Messages (ABAP)
Web Service (Performance)
ABAP Web Service Consumer
ABAP Web Service Provider
